ELECTRIC CONNECTER.

Application filed May 24, 1920. Serial No. 383,909.

To all whom *it may Concern.' l

Be it known that I, EUGENE A. KUEN, a

citizen of the United States, residing in Cin` cinnati, in the county of HamiltonV and State of Ohio, have invented certain new and useful improvements in Electric Connecters, of which the following is a specification."

My invention relates to electric connecters having two terminal posts, It is ythe object of my invention to provide novel means whereby to maintain the lateral relations between the posts, and between the posts and the tube, to prevent short-circuiting between them; and, further, to provide novel means whereby ready assembling of the parts is obtained; and the invention will be further readily understood from the following d'escription and claim, and from the drawings, I

' jects therefrom. A spring3l islocated bein which latter: Y

Fig. 2 is an edge elevation of the saine. Fig. 3 is a rear end elevation of the saine.

Fig. 4 is a front end elevation of the saine.

Fig. V5 is a longitudinal axial-section of the same, taken on the line 5-5 of Fig. l;

Fig. 6 is a cross-section of the same, taken on the line 6`6 of Fig. l.

Fig. 7 is a cross-section of the saine, taken on the line 7-7 of Fig. 4; and

Fig. 8 is a cross-section of the same,taken in the plane of the line 8 8 of F igl 7.

My improved device is especially applicable in connection with connecters used for electric lamps employing electric lamp bulbs having two end-terminals, and used as headlights, spot-lights, and the like, for automobiles and other vehicles. Such a bulb is exemplified at l1, having the end-terminals 12, 13, which connect with the filament of the lamp.

The connecter comprises a tube 15, which is adapted to be received and positioned Vin usual manner in a usual cylindrical flange at the rear end of the reiiector of the lamp. The plug 16 of the electric light bulb isreceived in the end of the tube, and has suitable mechanical connection therewith, instanced as a pin and bayonet connection slot 17.

An insulating block or Washer 2l, shown as a comparatively thin washer, for instance of insulating fibre, lis fixed in the tube, in suitable manner, as by means of indenting the body Vof the tube withy inwardly extending prongs 22, against which one end of the washer is received, and prongs 23 bent against the other end of the washer, for po-y sitioning the washer endwise-in theV tube. My invention'is especially useful when einployingthin libre washers which, inprac' tice, are comparatively inexpensive, and aid in maintaining 'the terminal posts in proper relation to the washer, vto each other, and to y the tube. i

Terminal posts 25, 26, are received through the washer. Each of thev posts'comprise a ksleeve 27, which is provided with an' annular shoulder 28 and a peripheral seat 29, which y latter is preferably of greater diameter than thediameter of the outer end l30 of the sleeve.

A plunger 33 is located in the sleeve and protween the bottom end of the bore 32 in the sleeve and the plunger. Y The plunger is provided with an inner annular shoulder 34, arranged to contact an annular flange 3 5 at the outer end of the bore, forming a'stopjfor lthe outward movement of the plunger, this stop being formed by spinning or upsetting the outeredge of t-he wall of the ybore after the plunger has been placed in the bore.

The insulatingl washer is provided with holes', 39, into which the endsof the: terminal posts are received, the posts :being forced into these holes so that the peripheral seats 29 make firm Contact with the walls of the holes, with the shoulders 28 bearing against one end of the washer. c

The outer end of each ofthe sleeves is provided with` a transverse hole 4l. An electric conductor`42 is provided with -an insulating covering 43. The insulatinglcovering, which is preferably a woven tubular fabric, isvremoved yfrom the eXtreme end of the electric conductor, so as ito electrically expose vthis end. The electric conductor is preferably a number of fine wires twisted or and a cupj Yiogs Y ing material Within the 'errule, and

to position the same endWise, 'for positioning the electric conducting Wire inthe tubular portion and the insulating covering in the cupportion.

The tubular portion isL inserted in 'the transverse 'hole Ain the terminal post, the

outer'annular shoulder 5l at the end ot the.

tubular portion impinging against the side ofthe terminal post. The outer end ot the electric conductor is bent across the outer end of thetu-bular lportion and thejopposite face of the-,terminal post, and across the end fthe terminal post, where the end of the Wireor Wires are' soldered to the end oit the termi-nal post by suitable solder, ,shown at 52. rlhis positions the end of the insulatthe endwise relation between the electric conductor, the insulating materiah'theerrule, and the post. lt further insures excellent electric connection between the electric conductor and the terminal post. The terrule aids in directingflexure of insupporting the electric conductor and insulating mat'eriahior preventingr abrupt bends therein, distinctly aided by the outwardly curved. Vflanged end ofthe cup-portion,

VAn insulating.- plate 55 isprovided with holes 56, in which the 'errules are located,

' positioning clip,

for 'positioning the errulcs with relation Ato each other, and controllingthe relative.po-V sitions'of the terrules, the insulating posts, and the tube. The insulating plate forms a and acts in connection with the insulating` washer' to maintain the terminal posts in parallel relation to prevent Short-.circuiting` between them, and vprevents the errules, as Well as the inner ends and the outer ends/of th terminal posts, from moving either toward or from each other! re- The parts are of simple construction and are readily and coiiyeniently` assembled.

y"rlayingv thus fully described my inffention, What l claim asnew andv desire to secure by Letters Patent, is.: l

ln an electric connecter, of a supporting` tube, an insulating body in said tube, pair said insulatingl` body, said terminalposts .the combination ci' electricterminal posts in provided with projections lextending` from(vk said insulatinp,1 bodyv outside said tube, elec tric conductors secured to said projections and extending at substantial right angles therefrom, and an insulating plate independent of said insulating'fbody and distanced therefrom, said insulating plate provided with spaced-apart holes, said insulating;Y ,plate extendingin a plane which is sub. stantially parallel with the single plane in which the longitudinalV axes otboth said projections extend, tors` located in sai'd holes, whereby vsaid .electric conductors and said projections are held in spaced-apart relations. o

ln testimony whereof, l have vhereunto si gned my name in the presence of .two scribing Witnesses. Y v d Y EUGENE A KUFJN litnesses:
